N-benzylazolium derivatives

ABSTRACT

N-Benzylazolium derivatives of the general formula (I), wherein Q is the remainder of an azole compound of the formula II  possessing antifungal activity; Z is nitrogen or methine; R1 and R2 are each independently a hydrogen atom or a group -OY [in which Y is a group easily hydrolyzable under physiological condition]; R3 and R4 are each independently a hydrogen or halogen atom, lower alkyl, lower alkoxy, lower alkylthio, (lower alkylcarbonyl)thiomethyl, carboxy or methoxycarbonyl; and X- is a pharmaceutically acceptable anion, as well as salts, hydrates or solvates of the compounds of the general formula (I) have antifungal properties.

BACKGROUND OF THE INVENTION

The present invention relates to novel azole compounds, processes for their manufacture, and antifungal compositions containing said azole compounds.

Although several azole compounds are currently used for systemic mycoses, none of them fulfills the necessary clinical requirement in full extent, i.e. efficacy against major systemic mycoses including disseminated aspergillosis, safety, and oral or parenteral formulations. Particularly, demand of a parenteral administration of the azole compounds is increasing for the treatment of serious systemic mycoses. Most of the azole compounds on the market as well as under development are highly lipophilic molecules that make the parenteral formulation difficult.

SUMMARY OF THE INVENTION

The present invention relates to novel water soluble azole compounds useful for the treatment of systemic mycoses and suitable for both oral and particularly parenteral administration, processes for their manufacture, antifungal compositions containing them and a method for treating mycoses having the general formulas (I) and (I'): ##STR3##

PROCESS A

The novel azole compounds represented by the general formula (I) as well as salts, hydrates or solvates thereof can be manufactured by reacting an azole compound possessing antifungal activity, of the general formula (II) ##STR11## with a compound of the general formula (III), ##STR12## wherein R¹ and R² are each independently a hydrogen atom or a group --OY in which Y is a group easily hydrolyzable under physiological conditions!; R³ and R⁴ are each independently a hydrogen or halogen atom, lower alkyl, lower alkoxy, lower alkylthio, (lower alkylcarbonyl) thiomethyl, carboxy or methoxycarbonyl; and L is a leaving group; or

PROCESS B

The novel azole compounds represented by the general formula (I) as well as salts, hydrates or solvates thereof can be manufactured by reacting a compound of the general formula (II) as defined above with a compound of the general formula (III) wherein one of R¹ or R² is hydroxy, followed by reaction of the resulting compound with a compound of formula R⁵ COL, or (R⁶ O)2POL, wherein R⁵ CO is the acyl residue of a N-protected amino acid, or R⁵ is hydrogen, lower alkoxy, lower alkyl which may be optionally substituted with carboxyl, amino, lower alkyl amino with or without protecting group, di-lower alkyl amino, or aryl; and R⁶ is hydrogen or lower alkyl, and L is a leaving group such as chlorine, bromine, OCOR⁵, methanesulfonyl, p-toluenesulfonyl and the like.

The reactions of processes A and B, of the compound of the general formula (II) with the compound of the general formula (III) can be carried out in a solvent such as methylene chloride, chloroform, benzene, toluene, acetonitrile, tetrahydrofuran, dioxane, or dimethylformamide, preferably chloroform, acetonitrile, or dimethylformamide.

The reaction time in the above benzylation reaction may be varied within a relatively wide range. In general, the reaction can be carried out at a temperature between 0° C. and 100° C., preferably between 0° C. and 50° C.

In process B, the acylation or phosphorylation can be performed with either free acid in the presence of a condensation agent such as 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and the like, or acid halides, acid anhydrides, mixed anhydrides, alkoxycarbonyl halides, dialkoxy phosphoryl chloride or phosphoryl chloride in the presence of an acid acceptor such as triethylamine, pyridine, picoline, lutidine, dimethylaminopyridine or alkali metal carbonate by the method known to those skilled in the art.

Preferably, an amino group present in R⁵ in the compound of formula III is protected by a suitable amino protecting group as tert.-butoxy carbonyl.

The protecting group may, if necessary, be removed after the reaction by procedures known to those skilled in the art.

The compounds of formula I may contain an amino acid ester substituent R¹ and/or R² which substituents may form acid addition salts. The term "salts of compounds of formula I" refers to such acid addition salts. These salts may be derived from pharmaceutically acceptable acids as described earlier with reference to the Symbol X⁻. The salt formation can be performed when removing a protecting group, or can be performed ad hoc by procedures known per se.

The hydration can be effected in the course of the manufacturing process or can occur gradually as a result of hygroscopic properties of an initially anhydrous product. Solvates with pharmaceutically acceptable solvents such as ethanol can be obtained for example, during crystallization.

The novel azole compounds represented by the general formula (I) as well as hydrates or solvates thereof have much higher water solubility than known antimycotic azole compounds he general formula (II) (see table 1).

In vivo efficacy of the compounds of the present invention is shown in Table 3. Male Fisher rats, strain F344/DuCrj, were employed for experimental infection models such as systemic candidiasis, systemic aspergillosis and pulmonary aspergillosis model. Immunocompetent 4 weeks old rats were used for systemic candidiasis or systemic aspergillosis which occurred after infection with Candida albicans conidia of 5×10⁶ /rat or with Aspergillus fumigatus conidia of 6×10⁵ /rat via tail vein. Otherwise for pulmonary aspergillosis model, rats had been immunosuppressed with cortisone acetate treatments prior to infection with 2×10⁵ /rat intratrachially. Treatments were given twice on the first day and once daily on following 4 days both for systemic and pulmonary aspergillosis. For systemic candidiasis rats were treated at 0, 4, 24, and 48 h after infection. Effective dose 50% (ED50) values were determined on day 14 after infection.

Therefore, the water soluble azole antifungal agents, represented by the general formula (I) as well as salts, hydrates or solvates thereof, according to the present invention, exhibit potent antifungal activity against various fungal infections including Aspergillosis in mice over a very wide range of dosages both orally and parenterally and are useful as antifungal agents.

The present invention further relates to the pharmaceutical compositions containing the azole compound of the general formula () as well as salts, hydrates or solvates thereof.

The azole compounds of the formula (I) as well as salts, hydrates or solvates thereof are very active antimycotic agents. They are active against a variety of fungal species including Candida spp., Cryptotoccus neoformanis, Aspergillus spp., Trichophyton spp., Microsporum spp., Exophiala spp., Blastomyces dermatitidis, and Histoplasma capsulatum.

Thus, the compounds of the present invention are useful for topical and systemic treatment of mycoses in animals as well as in humans. For example, they are useful in treating topical and mucosal fungal infections caused by, among other genera, Candida, Trichophyton, or Microsporum. They may also be used in the treatment of systemic fungal infections caused by, for example, Candida spp., Cryptococcus neoformans, Aspergillus spp., Paracoccidiodes spp., Sporotrix spp., Exophiala spp., Blastomyces spp., or Histoplasma spp.

For clinical use, the azole compound of the formula (I) as well as salts, hydrates or solvates thereof can be administered alone, but will generally be administered in pharmaceutical admixture formulated as appropriate to the particular use and purpose desired, by mixing excipient, binding agent, lubricant, disintegrating agent, coating material, emulsifier, suspending agent, solvent, stabilizer, absorption enhancer and/or ointment base. The admixture can be used for oral, injectable, rectal or topical administration.

Pharmaceutical formulation for oral administration may be granule, tablet, sugar coated tablet, capsule, pill, suspension or emulsion. For parenteral injection, for example, intravenously, intramuscularly or subcutaneously, the azoles of formula (I) may be used in the form of a sterile aqueous solution which may contain other substances, for example, salts or glucose to make the solution isotonic. The azoles can also be administered in the form of a suppository or pessary, or they may be applied topically in the form of a lotion, solution, cream, ointment or dusting powder.

The daily dosage level of the azole compounds of the formula (I) is from about 0.1 to about 50 mg/kg (in divided doses) when administered in one, two or more dosages by either the oral or parenteral route. Thus tablets or capsules of the compounds may contain from about 5 mg to about 0.5 g of active compound for administration. In any event the actual dosage can be determined by the physician and it may be varied upon the age, weight and response of the particular patient.

In addition, the azole compounds of the formula (I) as well as salts, hydrates or solvates thereof have activity against a variety of plant pathogenic fungi, including for example Pyricularia oryzae, Pythium aphanidermatum, Alternaria spp., and Paecilomyces variotii.

Thus, they can be applied for agricultural and horticultural purposes preferably in the form of a composition formulated as appropriate to the particular use and purpose desired, for example dusting powders, or granules, seed dressings, aqueous solutions, dispersions or emulsions, dips, sprays or aerosols. Such compositions may contain such conventional carriers, diluents or adjuvants as are known and acceptable in agriculture and horticulture. Other compounds having herbicidal or insecticidal, or additional antifungals can be incorporated in the compositions. The compounds and compositions can be applied in a number of ways, for example they can be applied directly to the plant foliage, stems, branches, seeds or roots or to the soil or other growing medium, and they may be used not only to eradicate the disease, but also prophylactically to protect the plants or seeds from attack.
